Which is completely unuseful as the device can be mapped to different
hardware later on.

It seems you are misunderstanding the purpose of udev. Its most
important benefit is to signal the user space that a device has been
plugged in, through HAL and dbus. The clean /dev tree is only a side
Furthermore, udev doesn't bring new problems. You can't have a
persistent naming scheme with a static /dev either, unless you are
loading modules by hand. If you still want to load your modules by hand,
udev won't prevent you from doing so.
